i foung them to be very good in my 97. really nice groups, but not very good in wind. they shot very flat. they also gave a high reading over the crono. they were efficient and could easy go over 12fpe in some guns, particularly springers which seem to shoot a lighter pellet with more power.
they would be good out to hunting ranges on a still day, but not so good for competitons. i find the jsb express 7.9s to shoot the best and exact 8.4s a very close second.
